- 📄 Perturbations of Black Holes Surrounded by Anisotropic Matter Field, Sagar J. C., Karthik R., Kartheek Hegde, K. M. Ajith, Shreyas Punacha, A. Naveena Kumara, Physical Review D, 111, 064034 (2025), DOI: https://doi.org/10.1103/PhysRevD.111.064034
This work investigates the quasinormal modes of a black hole surrounded by an anisotropic matter field under scalar and electromagnetic perturbations. It also examines the black hole shadow radius, Lyapunov exponent, greybody factors, and their relation to quasinormal modes in the eikonal approximation.
